Has anyone here actually used the mic included with some better receivers for their "callibration"? All of our receivers installed are usually too far away for the mic cord,ie remotely located. If you do use them how efficient would it be to locate the reeiver in the room temporarily to do the EQ and terminate the wires twice,(especially hard with in-wall-in-ceilings. Our do most people use their trained ear? Just curious.

Your a few days late. Go back a page or two, there was multi-page topic in this very subject just last week. Consesus was that some guys liked some brands, soe still iked their ears. Denon and Yamaha got the nods I believe.

thanks i'll check it out

If the receiver is placed in a different room use an SPL meter. You can get a pretty decent one from Radio Shack for 35 bucks.

I am not worried about SPL, more interested in surround sounding good given seating positions. Have worked with the DACs digital eq. with multiple mics part of the JBL synthesis issue and Audio Control Diva and was impressed. Just wanted to know if the manufac. mics. offer a low cost advantage or if they just do what a regular customer couldn't do with the OSD.

I don't want to speak for Mike, but he may have meant that the mono output on the side of the 'Shack SPL meter can be used in a pinch to go into the 1/8" mini-jack on the receiver with a cable that you supply (and a 1/8" mini-to-RCA adapter).

Since you are in the trade, I am sure you can fashion a longer length of audio cable top get you into another room....

Another option would be to use a high-res RTA like the AudioControl Iasys or the Gold Line DSP30 (with the 1/12th octave upgrade) and then just dial in the crossover points and parametric EQ on the receiver as you would your A-C Diva.

You can use the receivers' OSD and remote to make adjustments.

While it is not going to bring the results of an A-C Diva, the internal EQ systems can be pretty powerful when you combine them with real audio anylyzing tools and dial them in correctly.

I know that Denon gives info on using a mic and mic preamp. It's on their website. They tell you how to set the mic preamp level. You'll need a decent mike, my Behringer ECM8000 works pretty well, a mic preamp w phantom power, mic cable for the distance you need to go, and a couple adapters from the preamp to the input of the Denon. You'll also need a DVM for setting the preamp output level. With this solution, you can run lots of distance.

I'd be surprised if the other manufacturers wouldn't supply some directions for how to make a proper setup for their receivers.

I can fashion a longer cable easily but just wanted to know if it was worth it, just never tried them and trusted my ear. The Gold Line looks good, thanks for the info.

Do any of the current crop of mid-range receivers (Denon, Pioneer, etc) have the ability to do manual EQ'ing, WHILE using your own source of audio (ie noise/tone generator).

Awhile back we did a Denon, and we had to exit the setup menu to use our own audio. We had to make notes about each frequency (using the RTA), then go back into the setup menu, make a few changes, then go back and test again....

Sorta tedious.
